General Information and Connector Information General Information

1. For additional connection information, refer to the owner’s manual(s) for any component(s) connected to the di122 Digital Audio Decoder. 2. The Main AC Power going to the di122 and any other Wadia Component(s) should not be applied until all the system components are connected together. Failure to do so could result in malfunctioning of some or all of the system’s normal operations. When the di122 and other Wadia Components are in their Standby Power Off Mode, the Microprocessor’s Circuitry inside each component is active. 3. The Unbalanced Outputs and Balanced Outputs can be used simultaneously. 4. The di122’s internal Digital to Analog Converter Circuitry is designed to decode 2-channel PCM (Pulse Code Modulation) Digital Signal present at the Coaxial, Optical and USB Digital Inputs. Other Digital Audio Signal Format Types will cause the Audio Outputs of the di122 to be muted. 5. When discarding the unit, comply with local rules or regulations. Batteries should never be thrown away or incinerated but disposed of in accordance with the local regulations concerning battery disposal. 6. For additional information on the di122 and other Wadia Products please visit the Wadia Web Site at www.wadia.com.

Introduction and Performance Features Introduction

The Wadia di122 Digital Audio Decoder is one of the finest Digital to Analog Processors ever created with connections for digital sources including USB. The di122 Outputs have the ability to drive multiple components. The di122 reproduction is sonically transparent and absolutely accurate. The Wadia Sound is “The Sound of the Music Itself.”

Performance Features

• Dual Function Use the Wadia di122 as the Digital Preamplifer together with Digital Source Components and Power Amplifier1 to form a complete Audio System. Connect the Wadia di122 to an exisiting Analog Audio System to provide the latest in Digital-to-Analog Conversion from digital audio sources. • Electronic Input Switching Electronic Input Switching on all Inputs provides reliable, noiseless, distortion free switching. • Balanced Outputs The Balanced Outputs allow the connection of long cable lengths without a loss in sound quality. • Digital Audio Inputs The di122 has Coaxial, Optical and USB Digital Inputs to Decode PCM Signals from an external source. The Coaxial and Optical Inputs process Digital Signals up to 192kHz with 24Bit resolution. The USB Input process PCM Digital Signals up to 192kHz with Note: The Wadia di122 is designed to be compatible with the majority of Audio Power Amplifiers. However, due to a wide range of Power Amplifier Designs it is important the input sensitivity of the amplifier be at least 2 Volts. This will assure the playback of most music recordings are reproduced with adequate dynamic range.

32Bit resolution, decodes DSD128 Digital Signals and DXD 24Bit with a sampling rate of 352.8 (or 384). • ESS Digital to Analog Converter The patented SABRE32 HyperstreamTM DAC architecture and time Domain Jitter Eliminator is a 8 channel 32-bit, 192kHz Digital to Analog Converter. This assures the music is reproduced with a wide dynamic range and extremely low distortion for all Input Sources. • Precision Tracking Volume Control Volume levels are controlled by a Digitally Controlled Attenuator System. • Alphanumeric Fluorescent Display The Front Panel Information Display indicates the Source Selection, Bit Rate/Sampling Frequency and Volume Level. The display intensity is adjustable. • Remote Control The Remote Control provides control of the di122 operating functions. • Gold Plated Connectors The Output Connectors Contacts are gold plated for superior corrosion resistance and high electrical conductivity. • LED Front Panel Indicators Long life Light Emitting Diode (LED) is used to indicate when the di122 is in the Standby Mode. • Die Cast Aluminium Chasiss Ensures the durability and functional design of the di122 will be retained for many years. SABRE32 and Hyperstream are registerted trademarks of ESS Technology

The Sampling Rate and the Bit Rate is determined by the original recording and/or the Windows Application Settings for Output Format (when available). Note: In general, when the original music is recorded at a higher Sampling Rate, the result is usually more detail in the music. However, this higher rate results in consuming larger amounts of storage space. The Sample Rate usually should be set to match the Sample Rate of the music recording being played back.

There are many third party Windows Applications (besides Windows Media Player) for steaming music from the computer to Wadia di122 USB Input. An example of just one of the available applications is “JRiver Media Center”.
